Target pressure learn strategy for vehicular tire pressure systems
First Claim
1. A method for establishing the target pressure of each tire in a receiver memory, in a vehicular tire pressure monitoring system having a plurality of sensor/transmitters for sensing pressure and the receiver operable in a program mode, with one sensor/transmitter associated with each tire of the vehicle and having its own unique identification code, the method comprising the steps of:
- setting each tire on the vehicle to a desired target pressure;
causing the receiver to operate in a program mode;
triggering each sensor/transmitter to transmit an identification code and a target pressure signal representing the desired target pressure of the tire associated with that sensor/transmitter;
storing the target pressure signal in the receiver; and
causing the receiver to exit its program mode.

Abstract
A method of establishing a target pressure for a vehicle tire for storage in a receiver having a microcontroller where a sensor/transmitter combination is mounted on each wheel. After each tire is inflated to the target pressure the sensor/transmitters are sequentially triggered to send an identification code and a target pressure signal to the receiver for storage in memory. In an alternate embodiment, the target tire pressures are statistically averaged and a warning signal is generated if a single tire target pressure deviates a predetermined amount from the statistical average.

4. A method to establish one or more target tire pressure signals for storage in a receiver in a vehicle tire pressure monitoring system having a sensor/transmitter located in each tire comprising the steps of:
-
setting a tire pressure in each tire to a desired target pressure;
causing the receiver to operate in a program mode;
triggering each sensor/transmitter in a specific order according to a tire'"'"'s location on the vehicle to transmit an identification code and a pressure signal representing the desired target pressure of the tire;
receiving, processing and storing the pressure signal in the receiver; and
causing the receiver to exit the program mode. - View Dependent Claims (5)
calculating an average target pressure value of all the pressure signals;
comparing the pressure signals from each tire with the average target pressure value; and
displaying a warning signal if one or more of the pressure signals differs from the average target pressure value by at least a predetermined amount.
